Be "it known that I, Mn'rrrrrnw Vmnnnonn, a citizen of the UnitedStates, and a 1:631 dent/of Brooklyn, in the county of Kings and Potatoof New York, have invented certain new and useful Improvements in Manchines for Applying Patches and Fasteners to Envelope, of which thefollowing 18 a specitieatiom.

My invention relates to that class of machines in which the nlasps andpatches for receiving said clasps are applied to the -enveiops by thesame operation, the pr mary object of this invention being toprovlde animproved construction, combination and arrangement of parts, which willoperate in an improved manner to swure the spurs of the fastener to theenvelop and which will be adapted to :permit the necessary hdJtlStmerits between the-fastener feeding and the SPMIHSGGUD-lfig devicesto meet the require ments of various sizes of envelops, whale at thesame time maintaining the proper relationship between the mechanisms forat teaching the clasps and washer patches. =0ther and further objectswill appear in the specification and be specifically pointed out in theannexed claims, reference being had to the accompanying drawingsexemplifying the invention .in its application to a well known type ofclasp envelop.

in the drawings Figure 1 is a front elevation of a machine constructedin accordance with the principles of the present invention. Fig. 2 is aside elevation of the same, parts being broken away to more clearly showother parts 'of' the machine. Fig. 3 is altop plan view of the same.Fig. 4 is .a fragmentary detail elevation of parts shown in Fig. 2 on anenlarged scale. 5 is an end elevation of the parts shown in Fig. at,corresponding with the point of view of Fig. 1. Fig. '6 is an enlargeddetail elevation of parts shown in Fig. 4. Fig. 7 is an end elevationof-thesarne. Fig. 8 is a fragmentary top plan view corresponding to Fig.3. Fig. 9 is a fragmentary front. elevation of details shown in Fig. 8.Fig. 16 is a detail plan view of. the anvil plate for deflecting thespurs of-the clasp and a transverse sectionlof the same, and Fig. 11 isa plan view of a clasp envelop with the flap-open. l

Referringmore particularly -to the. drawin-gs s udio the embodimentsshown therein, the legs 1 support-a main bed plate :2. Prom jectingupwardly from the base plate 2 are spaced bearing lugs 3 in which isjournaled :a main drive shaft or cam shaft a, said shaft being providedon one'end with a drivung pulley 5 provided with a clutch element (6which is movable into and out of engageunent with a clutch element '7,which is re .ciproca-ble along the shaft 4 under the acltion of "aspring 8 outo f the right hand [bearing log 3. The pulley 5 turnstfreely on the shaft 4 while the clutch eleunent 7 is connected to theshaft by means of a spline (not shown on the drawings). A earn plate 8is integrally formed with the clutch element 7 being cooperativelyrelated to a stop pin 9, which is normally aretained in upper positionby a spring 10 which thus serves to hold the clutch elements 6 and 7apart. A treadle lever 11 pivoted at 12 to the leg 1 has its outer endconnected by a connecting-rod 18 with the stop pin 9 to permit theclutch elementsfi and 7 to be thrown into engagement. A tie bar 14 whichextends between two of the legs 1 (see Fig. 1) is provided with astandard 15 having a vertical slot 16 within which is verticallyadjustable a bolt 17 which serves to secure the depending flange 18 ofan envelop supporting bracket 19 to the standard 15. The bracket 19 isprovided with aside rail 20 for affording lateral support to the envelop21 as it is moved into and out of position in the machine as sho n inFig. 2.

As shown most clearly in Figs. 2 and 3 a horn 22 is rigidly mounted uponthe base plate 2 by having its relatively heavy pad block 23 secured toone of a plurality of spaced bars 24:. As shown best in Figs. 6, 7, 8, 9and 10, this horn 22 comprises a plate 25 whichis pointed at its outerend and is provided with a dove-tailed groove 25 for reciprocablymounting a slide 26 carrying an anvil plate 26. The slide 26 is providedwith a pin 27 which projects into a slot 28 in the end of a crank arm 29which is rigidly connected to an oscillatable rod 30. Projecting fromthe inner face of the anvil 26' is a pin 27 a which moves in alongitudinal slot 26 in the slide 26 when the anvil is adjusted on saidslide in the manner to be hereinafter pointedout. As shown in Fig.

2 the rod 30 derives its power through a crank arm 31 which is keyed tothe rod. 30

and has its onterend pivotally connected with an operating lever 32 therear end of which is provided with a yoke 33'which slidably engages theshaft 4. Lever 32 carries a cam roller 34 which runs on a cam 35. Inorder to provide simple and eflicient means for shifting the claspfasteners successively into position to be secured to the envelops whichare disposed one after another over the horn as shown in Fig. 2, thefasteners are manufactured in such a way as to form a continuous sheetmetal ribbon which is conveniently handled by having it coiled into aroll 36, said roll being preferably journaled on a pin 37 which projectslaterally from the upright 38 of an angular pedestal or support, thehorizontal arm 39 of said support being provided with a slot 40 whichpermits it to be adjusted laterally with respect to the plane in whichthe clenching operation to be presently described, takes place. A stud41 extends through said slot 40 being threaded into the superstructure42 of a frame 43 which is secured to the main bed plate 2 by meansofbolts 44. Integrally formed with the superstructure 42 of the frame43, are a pair of spaced overhanging bracket arms 45 which carry a bar46 which is adjustable laterally with respect tothe ribbon or band 36.Interposed between the bracket arms 45 is a collar 47 which carries aset screw 48 which is adapted to lock the bar 46 in any position towhich it may be adjusted. In th1s "manner the clasp tape is madeadjustable toward and away from the plane of the patch washer tape to behereinafter referred to, thus adapting the machine to be used withenvelops of various sizes. Depending from the squared extremity 49 ofthe bar 46 is a guide or chute 50 through which the clasp tape is fed bymeans of claw 51 which is pivoted at 52 to the outer end of a lever arm53 which is oscillated by a shaft 54 from one end of which projects aradial arm 55 which is connected by a spring 56 with a fixed pin 57.Said'shaft 54 is journaled in the upper ends of a pair of spacedstandards 58 which are rigid with the bed plate 2. A cam arm 59 which iskeyed to the shaft 54'is provided on its outer end with a cam roller 60which runs on the periphery of a cam 61 and thus serves to impart the upand down movement to the claw 51 which is held resiliently 'to its workby a spring 62 carried by the crank arm 53. A spring dog 63 is securedto the square end 49 of the bar 46 for preventing retrograde movement ofthe clasp tape 36.

Referring again to Figs. 6 to 10 inclusive,

the chute 5O embodies a central guide rail 64 over which the connectedclasps are fed until the nibs or spurs 65 reach a pair oflateralrecesses or openings 66 in theguide when a pair of bending blades orplates 67 carried by a reciprocating shaft 68 engage said spurs todeflect them inwardly toward the horn or shear 69 of the rail 64. Theplates or blades 67 are rigidly secured to a stamping head 69which is inturn rigidly I cesses 70 in the anvil plate 26'. When the I stampinghead 69 is again moved toward the anvil plate 26, the spurs 65 areforced through the wall of the envelop which is disposed over thebifurcated leaf spring 71,

which is embedded at one end in the plate v 26. As the stamping headagain recedes, the spring 71 forces the envelop with its clasp outwardlywhile at approximately the same time, the plate 26 is moved endwise bythe oscillating rod 30 which brings the solid neath the central portionof the fastener so that the next inward movement of the stamping head 69clenches the spurs 65 in position. As each of the fasteners is forcedoutwardly by the spring 71, the soft flexible nature of the spurs 65,permit the fastener to be readily disengaged from the beveled tonguebetween the recesses 70, the extremities of said spurs being stilldeflected to some extent toward each other. When therefore the fasteneris driven against the table portion of the anvil, said spurs areclenched into place. During the first infiat portion at the left end ofplate 25 beward movement of the stamping head 69',-c/'

the sharp corner 72 coiiperates with the' sharp corner 73 on the end ofthe shear 69 to shear the lowermost clasp from the ribbon. In order toimpart the reciprocatory movement to the rod 68 and stamping head 69,said rod' 68 has its outer end in operative engagement with a crank arm74 which is keyed to a rock shaft 75 which is journaled in brackets 76rigid with the bed plate 2. A-rock arm 77 keyed to the shaft 75 isprovided with a cam roller 78 which runs on a lateral face cam 79.Secured to the extensions 80 of the bed plate 2 are ,a'pair ofoppositely disposed punch blocks 81 having their adjacent ends providedwith hearing bosses 82 through which the hollow disk punching rods 83are reciprocated by the operating levers 84 which are pivoted on thepins 85, removably socketed in the bed plate 2-. A punch rod 86 extendsthrough one of the punch rods 83, being reciprocated by the operatinglever 87 pivoted on the removable pin 88. The operating levers 84 and 87are provided with open forks at their swinging ends which embrace therespective rods 83 and 86. Each of said operating lovers are moreoverprovided with cam arms 89 (shown in dotted lines in Fig. 3) whichmore-me slide in the slots 90 between the cam blocks 91 carried by thepower shaft 4. This construction permits the instant removal of the camlevers whenever desired. In order to properly set the operating leverswith respect to the punch rods, each of said rods is threaded exteriorlyand provided with a pair of adjustable abutment nuts 92 for each lever.Rolls 93 of disk-forming tape are journaled on pins 94: said tapes beingmade to pass upwardly around guide pulleys 95 and thence .to gummingrolls 96. Said tapes can be drawn close about the rolls 96 by means oftightening forks 97 pivoted at 98. After leaving the guide rollers 99,the tapes are drawn upwardly through the bosses 82, each of said bossesbeing provided with a throughW-ay 100 as shown in Fig. 8,*

being thus guided on opposite sides of the extended flap of the envelop.quence as the oppositely disposed punch bars 83 move toward each other,each cuts from one or the other of tapes 93, an annular reinforcementdisk which has been previously gummed. As these disks are glued toopposite faces of the flap, the punching rod 86 perforates the flap. 1

in order td provide simple and eflicient means for adjusting thereciprocating movements of theanvil with respect to the path traveled bythe band of fasteners, the outer end of the slide 26 is provided with alongitudinal series of holes 101. Into any one of these holes a screw102 is adapted to be threaded, said screw being mounted in a countersunkaperture in the outer end of the anvil plate 26.

The operation of my improved machine has been brought out in theforegoingdescription. Briefly stated the advantageous results accruingfrom a machine embodying the present invention are as follower Theimproved method whereby the clasp and re inforcement disks are appliedsimultane ously and at accurately predetermined distances apart is madepossible by the employment of a single rigid member such as the horn 25,provided with means for locating both the clasp and reinforcing disk.Zlo adapt the machine fordiiferentsizes of envelops, the clasp applyingdevice is adjustable toward and away from the disk applying apparatus.Collateral with these, the
